On Mac OS X, controlling the number of processor cores used by COMSOL is only possible when launching COMSOL from the Terminal application. The default behavior is to use all available physical processor cores for the COMSOL Multiphysics application. You can find how many processor cores you have in the System Profiler application, or by using the command sysctl hw.ncpu. You can override the default by using the command line switches. For example, start COMSOL with 2 threads using the command /Applications/COMSOL61/Multiphysics/bin/comsol -np 2.
On Linux the default behavior is to use all available physical cores for the COMSOL Multiphysics application. You can override the default behavior by using the command line switches. For example, start by the command comsol -np 2.
Go to the Config Services page. Change the paths to lmgrd.exe, and license.dat so that they all point to the COMSOL 6.1 installation directory. Starting with the version of the Flexnet distributed with COMSOL Multiphysics 5.4, the permissions where the license manager is allowed to write has been changed. The current recommendation is to store the debug log file, comsol61.log in the directory C:\ProgramData\COMSOL.
Stop the COMSOL license manager: Make the comsol60/multiphysics/license/$arch directory the current directory, where $arch is either glnxa64 (64-bit Linux), glnxarm64 (ARM Linux), maci64 (64-bit macOS), or macarm64 (ARM macOS). Stop the 6.0 license manager with the lmdown command:
COMSOL Multiphysics is built and tested with the above C/C++ compilers. Please note that later versions of those C/C++ compilers may also be compatible with the external C interfaces. When using the COMSOL API for use with Java API in client/server mode with the jar files listed in /bin/comsolclientpath.txt, JRE 8 and 11 are supported. When using the COMSOL API for use with Java API in standalone mode with the jar files listed in /bin/comsolpath.txt, JRE 11 is supported.
Because your /home directory is limited in space, it is a good idea to move and symlink the /.comsol directory to your /data directory, where there is a much largeramount of disk space available. This can be done like this:
As of July 2021, the Department of Chemical Engineering participates in a shared comsol license with other departments across the college and University. The teaching license (CKL) is available to anyone on-campus and does not require any registration or special configuration. The research license (FNL) is limited to registered users only, by Andrew ID. The username on your computer MUST match your Andrew ID. Faculty and PhD students are registered for the research license by default. Anyone else that needs to use this license must request access by sending an email to cheme-c...@andrew.cmu.edu .
4. When prompted for license information, use the drop-down menu labeled license format and select @. Input 1718 for the port number and comsol.andrew.cmu.edu for the host name. Click Next.
